BALL-COCK VALVE.

Specication of Letters Patent.

Patented April 9, 1907.

Application iled December 6, 1905. Serial No. 290,595.

To au whom t may concern:

Be it known that I, CHARLES A. TAYLOR, a citizen of the United States,residing .at Madison, in the county of Somerset, State of Maine, haveinvented certain new and useful Improvements in Ball-Cock Valves, ofwhich the following is a specification, reference being had therein tothe accompanying drawings. j

This invention relates to a ball-cock valve,

and particularly to a float-controlled con-` structionadapted forapplication to cisterns or tanks.

The invention has for an object to provide an improved construction andarrangement of parts by which more eHicient results are secured in theconnection between the fioatlever and the valve controlled thereby, soas to secure a positive operation with a minimum of friction and effecta tight joint between the valve-casing and the cistern or tank to whichit is applied.

Other and further objects and advantages of the invention will behereinafter fully set forth and particularly defined by the appendedclaims.

In the drawings, Figure 1 is a perspective of the invention. Fig. 2 is acentral vertical section. Fig. 3 is a detail perspective of thevalve-casing. Fig. 4 is a similar view of the crank-lever. Fig. 5 is adetail perspective of the valve-head, and Fig. 6 is a similar view ofthe valve.

Like numerals of reference indicate like parts throughout the severalviews of the drawings. j

The numeral 1 designates a sleeve or connection adapted for insertion inthe lower part `of a tank or cistern 2 and interiorly threaded at itsupper portion, as shown at 3. The lower portion of the sleeve iseXteriorly threaded, as at 4, and a clamping-nut 5 may be appliedthereto in the usual manner. Oooperating with the threaded portion 3 isa valve casing or seat, eXteriorly threaded to engage with the sleeve,and provided with an enlarged cap 7, beneath which a Washer 8, of anydesiredmaterial, maybe disposed, so that when the valve-seat is screwedinto the sleeve the washer is compressed and an absolutely tight jointeffected between the cistern or tank and the sleeve inserted therein.The valve-casing is provided with one or more passages 9 therethroughand with a central opening 10, through whichthe stem 11 of valve 12extends. This valve is provided with passages 13 therethrough, adaptedto be brought into alinementwith the passages 9 in the rotation of thevalve. The valvestem is provided with a seat 1 4 at its upper portion,upon which a head 15 rests and is secured, while interposed between thehead and the top of the casing is a coil-spring 16 by which the valve isnormally held in close contact with its seat.

The head 15 may, as shown, be formed concave, so that the liquid passingthrough the valve will strike the same and be deflected toward thebottom of the cistern, thus avoiding any spurting of the liquid or pipeconnection at that point. The head 15 is provided at one side with aradially-extending lug 17, constituting a lever from the valve 12, bywhich the latter may be rotated. The cap of the valve-casing is likewiseprovided at one side with a bracket 18, having a depending lug 19,through which a pivot 20 is adapted to pass for the purpose of pivotallymounting the crank-lever 21 in said bracket. One arm, 22, of this leveris adapted to receive the usual iioat and rod for the purpose ofactuating the valve, while the other arm, 23, is slotted longitudinally,as shown at 24, and adapted to receive in said slot the lug 17 of thevalve-head. The under face of the arm 23 is properly curved to providefor a free travel thereof and formed at opposite ends with stops 26,adapted to engage the base 27 of the bracket 18 in order to limit themovement of Ythe crank-lever in opposite directions.

In the operation of the invention the rising and falling of the iioatoscillates the cranklever, which, by reason of the slotted connectionwith the valve-head, rotates the valve for the purpose of admitting orcutting off the flow of liquid to the tank. This slotted connectionprovides a simple and efiicient construction for shifting the valve andavoids the friction of a geared connection, and provides a positiveconnection adapted to be limited in its travel for ef- The constructionof the valve-casing and the manner of mounting the same on the sleeveprovides a tight joint between the several parts and the cistern or tankto which they are applied.

Having now described my invention and set forth its merits, what Iclaim, and desire to secure by Letters Patent, is

l. The combination with a valve-casing, of a pivoted valve mountedtherein and capable of a reciprocatory movement in the direction of itsaxis of rotation, said valve having a lever-arm extended in a directiontransverse to its axis of rotation, a pivotal operating-lever whose axisof rotation is transverse to the direction of said reciprocatorymovement having an arm slotted in a direction transverse to its axis ofrotation, the slot in said arm engaging the lever-arm on said valve tomove it about its pivot and lying in one position in the path of saidleverarm in the reciprocatory movement of the valve.

2. The combination'with a valve-casing, of a rotary valve mountedtherein for reciprocative movement and having a laterally-disposedlever, a bracket vertically disposed at one side oi said casing andhaving a stop portion at its base, an angle-lever mounted in saidbracket and provided with a iioat-arm and a dependinglongitudinallyslotted arm to embrace said valve-lever, and stops carriedby said slotted arm at opposite sides of the base to engage the stopportion thereof.

3. A valve comprising a casing, a rotary valve mounted therein andprovided with a lever. extending therefrom, a bracket, a crank-levermounted in said bracket and provided with a slotted depending arm toreoeive said valve-lever, and stops disposed upon said arm at oppositesides oi the slot therein to engage a portion of said bracket.

4. A valve comprising a valve-casing having a passage therethrough, arotary valve provided with an apertured Jface in Contact with the innerJface of said casing, a valvestem extended through said casing, avalvehead secured to said stem and provided with a concave under faceabove the passage in the valve-casing, a tension-spring disposed betweensaid head and casing to retain the apertured face in Contact, and meansfor oscillating the parts of said valve.

In testimony whereof I aHiX my signature in presence of two witnesses.
